Pay-per-call employee data API on Base via x402, settled in USDC at $0.02/request.
What it does
This endpoint at lowpaymentfee.com provides access to employee data (specifically employee record #107) via the x402 payment protocol. It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) with a maximum cost of 20,000 base units, which equals $0.02 per request (USDC uses 6 decimals).
The broader lowpaymentfee.com platform advertises a wide catalog of pay-per-call APIs spanning data & analytics, AI/ML (sentiment analysis, summarization, classification, embeddings), finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). All endpoints are listed at $0.02 per request with no API keys, no rate limits, and no minimum commitments required.
This specific endpoint (/api/v1/employees/107) is not listed on the site's main catalog page, so it may be a demo or sample resource. The probe confirmed a live 402 challenge with a valid x402 v1 payment envelope. Documentation pages (/docs, /pricing, /README) returned only a "Connect wallet" prompt with no substantive content, so the actual response schema and employee data fields are unknown.

Quality
The endpoint is live and returns a valid x402 challenge, but there is no OpenAPI schema, no documentation of request/response fields, and the /docs, /pricing, and /README pages are empty stubs. The specific employee endpoint is not listed in the site's own catalog. Effectively a stub listing with confirmed liveness.
